# Sailing Instruments

The instrument panel provides real-time data from your sensors and boat polars.

## Wind Data
- **AWS (Apparent Wind Speed):** The wind speed felt by the boat.
- **TWS (True Wind Speed):** The actual wind speed across the water.
- **TWD (True Wind Direction):** The compass direction the wind is blowing from.

## Boat Performance
- **BSP (Boat Speed):** Speed through the water (from your speedo).
- **SOG (Speed Over Ground):** Actual speed relative to the earth (from GPS).
- **VMG (Velocity Made Good):** Speed directly upwind or downwind.
- **Polar %:** Your current speed relative to the theoretical maximum for your boat.

## Navigation
- **HDG (Heading):** The direction the bow is pointing.
- **COG (Course Over Ground):** The actual path the boat is tracking (includes leeway and current).
- **Depth:** Current depth below the keel.
